Мultiply both sides by 3x if 1/(3x) or by 3 if (1/3)x

Calculus ll
f'x=e^2y (e^2y-const) f'y=2xe^2y (x-const)

COLLEGE ALGEBRA ..HELP!
Don't worry sometimes it happens that 2*2=5

COLLEGE ALGEBRA ..HELP!
x^2+11/12x=5/12 x^2+2*(11/24)*x+(11/24)^2=5/12+(11/24)^2 (x+11/24)^2=(19/24)^2 x+11/24=19/24 or x+11/24=-19/24

pre calc
Solve the system: a*0^3+b*0^2+c*0+d=-4 a*1^3+b*1^2+c*1+d=-8 a*(-1)^3+b+(-1)^2+c*(-1)+d=-8 a*2^3+b*2^2+c*2+d=-2 d=-4 a+b+c+d=-8 -a+b-c+d=-8 8a+4b+2c+d=-2 Add the 2nd and the 3rd: 2b+2d=-16 d=-4 b=-4 a+c=0 8a+2c=18 Subtract from the 4th 2*3rd: 6a=18 a=3, b=-4, c=-3, d=-4

maths (trigonometry)
Q2)Because sina, cosa, tana - g.p. cos^2(a)=sina*tana=sin^2(a)/cosa cos^2(a)=(1-cos^2(a))/cosa cos^3(a)=1-cos^2(a)

Math quick check thx
